La función sustituida es:

\(Z:\ 10\left(5\right)+2\left(10\right)+20\left(0\right)+11\left(0\right)+7\left(0\right)+9\left(5\right)+20\left(15\right)+12\left(5\right)+4\left(0\right)+14\left(0\right)+16\left(0\right)+18\left(10\right)\)
\(Z:\ 10\left(5\right)+2\left(10\right)+9\left(5\right)+20\left(15\right)+12\left(5\right)+18\left(10\right)\)
\(=50+20+45+300+60+180=655.\)
